– enable new options InsertNewlineAtEOF and RemoveSemicolon
– reformat the code accordingly

There was some overengineering related to the Hook class.

– under Linux and macOS, use the “dynare” subdirectory of the configuration
  directory specified by the XDG specification
– under Windows, use the “dynare” subdirectory of the Application Data folder

The old location is kept for backward compatibility, with a warning.

In particular, makes clearer the distinction between configuration and
configuration file. The former includes information that is not in the
latter (command-line options.)

Automatically detected using clang-tidy with bugprone-reserved-identifier
check.

By the way, homogeneize the define identifiers in relation to camel case
convention.

Automatically detected using clang-tidy with modernize-use-nodiscard check.

A function defined entirely inside a class/struct/union definition is
implicitly an inline function.

For a rationale, see http://www.sjbrown.co.uk/2004/05/01/always-use-explicit/

- no longer use pointers
- use pass-by-value when possible
- use range-for loops when possible

Those were not automatically replaced by clang-tidy, I don’t know why…

In C++11, it is no longer necessary to put a space between two consecutive ">".

Performed using modernize-pass-by-value from clang-tidy.

Manual intervention was needed to fix an issue in MacroValue.hh.
Also replace std::move by move, since we import the std namespace.
